FIELD OF THE INVENTION The present invention relates to a data setting system for a terminal unit in a remote monitoring and control system. The present invention relates in particular to centralized control over two-wire lines in order to understand monitoring, control, and time division and multiplexing of similar data. The present invention relates to a system for setting data for a terminal unit in a system for remotely monitoring and controlling loads on terminal units respectively connected to the apparatus.

Remote monitoring and control systems of the kind mentioned are effectively used in lighting control systems, fire protection and security systems, etc. mounted in structures.

In the monitoring and control system of the kind mentioned, the terminal unit is provided with a setting component which is individually adjustable such that various data can be stored in the memory section of the terminal unit or that the stored data can be modified, usually by manual operation of the component. . On the other hand, the installation position of the terminal unit was very complicated in data storage or changing operation when the unit was a place such as a ceiling ceiling or a very narrow space which could not be easily accessed by the system operator.

In US Pat. No. 4,535,333 to Joseph W. Twardowski, a control device using a so-called transceiver system used to remotely open and close a garage door has been proposed, where data setting or modification is achieved by opening or closing the garage door in any desired manner. It is also made between the transmitter and the receiver included in the system so that it can be realized. In addition, another system was published in US Pat. No. 4,807,052 to Toshio Amano, where, for example, a remotely controlled object is written to a non-volatile memory that is modulated in response to optical radio transmission from data stored in the memory, i.e. from a writing means. A nonvolatile memory is provided to be operable as controlled according to the control data.

However, any of the above-mentioned US patents allows control data and the like in the receiver and controlled object to be written and transferred from a remote location, i.e. changed, while the Twar-dowski patent is not suitable for optical radio transmission and reception, The Amano patent is still far from time division and multiplexing of data such as monitoring and control, especially address setting systems via optical wireless transmission and reception systems. Therefore, in order to improve remote monitoring and control, a data setting system for a terminal unit, that is, a setting system for setting address data and the like by optical radio transmission and reception, is required in a remote monitoring and control system using multiple data transmissions. come.

Therefore, a main object of the present invention is to provide a system that can easily set data at a remote location in a terminal unit equipped with a nonvolatile memory by optical radio transmission and reception in a remote monitoring and control system using multiple transmissions. .

According to the present invention, the object is that a plurality of terminal units each having a set address are connected to the central control unit via two wires, and time division and multiple data transmission are performed between the central control unit and the terminal unit. It can be realized by a data setting system for a terminal unit in a remote monitoring and control system, which is carried out with a transmission signal transmitted from the device, where each terminal unit stores the data to be written into the memory and the memory for holding various functional data. An optical receiver is provided for receiving an optical radio signal, the optical radio signal is prepared in an operating means provided separately from the terminal unit for transmission to the terminal unit, and the function of each terminal unit is switched in accordance with the function data in the memory. do.

Referring to FIG. 1, this remote monitoring and control system is generally a two-wire signal line 13 connected to, for example, the wiring board 11, the relay controller 12, the wiring board 11 and the controller 12. And a central control unit 14 included in the wiring board 11 and connected to the signal line 13, wherein the monitoring terminal units 15a, 15b, 15n, control terminal units 16a, 16b, 17a, Various terminal units, such as 17b and ..., 18a, 18b, ...), external-interface connection terminal unit 19, pattern setting terminal unit, etc., are connected to the signal line 13, and each terminal unit is, for example, It is appropriately arranged in a room or the like and has an individual set address. The optical wireless data signal line 21 and the data relay terminal unit 22 connected thereto are also connected to the signal line 13.

In this example, the switches SW1, SW11, SW12 and SW21 to SW24, which are wall switches installed on the indoor wall, are respectively connected to the terminal switches 15a, 15b, ..., 15n independently or in common, The loads L1, L11, L12, L21 and L22 and the remote control relays LY11, LY12, LY21, LY22 and LY23 are connected to the control terminal units 16a, 16b, 17a, 17b, and 18a, 18b, ...

On the other hand, each terminal unit, when its set address data matches the address data of the transmission signal Vs received via the two-wire signal line 13, the unit receives control data of the received transmission signal Vs. The monitoring data signal as a current mode signal (a signal sent as shorted through the appropriate low impedance in the signal line 13) is sent to the central control unit 14 in synchronization with the return signal period WT of the transmission signal Vs. Provided to send. The central control unit 14 interrupts from any one of the dummy signal transmitting means which always transmits the dummy transmission signal in which the mode data signal MD is in the dummy mode, and the terminal unit as shown in FIG. 2 (b). Upon receipt of the signal Vi, access is gained to this terminal unit in order to detect the specific terminal unit that generated the interrupt signal and take its own monitoring data sent from it.

From the monitoring terminal units 15a, 15b, ..., 15n, the external-interface connection terminal unit 19, the pattern setting terminal unit 20 or the optical wireless data relay terminal unit 22, the central control unit 14 Based on the monitoring data respectively sent to the control unit, the central control unit 14 controls the control terminal units 16a, 16b, ..., 17a, 17b, ..., and 18a to control corresponding one or more of the loads L1 to L22. 18b,... Prepare control data to be transmitted to any one or more of them, and transmit the control data so prepared via time division multiplexing to the specific control terminal unit through time division multiplexing so that the corresponding loads L1 to L22 are optimally controlled. Send. When appropriate data is then transmitted from the optical radio transmitters 25a and 25b to the optical radio receivers 26a to 26c, the data is transmitted to the central control unit 14 via the signal line 21 and the data relay terminal unit 22. do. The external-interface connection terminal unit 19 is provided for data transmission to the external control unit 23, and the pattern setting terminal unit 20 transmits the pattern control data provided as input from the data input means 24 to the central control unit. 14 is provided for transmission.

Since various functional terminal units are used simultaneously in the system described above and the provision of interfaces to all terminal units greatly complicates the overall system arrangement, the input / output means and appropriate parameters for each terminal unit to function according to the parameters performed. It is desirable to provide a memory for storing the memory. For these parameters, for example, address specific to the terminal unit, terminal unit type (for monitoring, control, etc.), input polarity (positive logic and negative logic), input latch mode (rising latch, change point latch, change point correction, etc.) Accompanying latches), number of input samplings, output polarity (positive logic and negative logic), output mode (single relay drive output, ratchet drive output, one-shot pulse output, flicker lamp drive output, etc.), output time (relay drive time) ), Reply output mode (3-way setting, bit division, etc.), dimming mode (phase control dimmer, inverter control dimmer, etc.), one-shot or delayed lighting delay time, and the like.

Here, it has been required that the storage of data in the memory of the terminal unit or any modification of the data stored in the memory can be achieved from the remote location.

According to the present invention, a data setting system for a terminal unit can be provided which satisfies the above requirement and can be used in the remote monitoring and control system shown in FIG.

Referring to FIG. 3, there is shown a terminal unit 30 and an operating device 31 usable as supervisory terminal units 15a, 15b, ..., 15n in the system described above. The terminal unit 30 incorporates transmission and reception means 32 and an interface for transmitting and receiving the above-described transmission signal Vs transmitted through the two-wire signal line 13 in the system of FIG. And a memory means 34 for setting the contents of data processed by the signal processor 33. The terminal unit 30 emits light indicating the ON and OFF states of the optical receiver 35 and the optical emitter 36 and the load L which transmit and receive an optical radio signal such as infrared rays to the operating device 31. Further switches SW such as diodes LD1 and LD2 and a wall switch are provided.

Here, the signal processor 33 preferably includes a microcomputer arranged to compare the address data provided from the central control unit 14 of the system of FIG. 1 with the preset address data of the terminal unit 30. If there is a match in the address data, the ON or OFF state of the switch SW is read, and the read state is sent to the central control unit as a monitoring signal in synchronization with the transfer standby signal. The address data set in the terminal unit 30 can be set by connecting a DIP switch to the signal processor 33, but is preferably written to the memory means 34 so that the data can be used.

As the memory means 34, it is optimal to use a nonvolatile EEPROM, which is a kind of memory switch for switching the processing executed in the signal processor 33 to operate according to the above-mentioned parameters. The programs required for the various functions are preferably provided to the signal processor 33 together with the interface but they may be included in the memory means 34.

In addition, an operating device 31, such as a remote control device, is provided with an optical emitter 37 and an optical receiver 38 for transmitting and receiving optical wireless signals between the device 31 and the terminal unit 30, and an optical emitter. The optical radio signal transmitted from the emitter 37 is provided as an input signal from the operating means 40 and processed by the signal processor 39 in the apparatus 31. The optical radio signal received at the optical receiver 38 is also processed in the signal processor 39 and the device 31 is provided with display means 41 for displaying the signal so processed.

The basic operation of the data setting system for the terminal unit as shown in FIG. 3 will be described next with reference to FIG. As the terminal unit 30 is connected to a power source, the data stored in the memory 34 is read to set the function of the terminal unit 30, and normal operation is executed in accordance with the set function, during which the optical radio Detect if a signal is received. If there is a reception of the optical radio signal and the mode is in the seti mode, the signal is written to the memory means 34 and then the data in the memory means 34 is read and sent to the operating device 31. When the optical radio signal from the operating device 31 is in the confirmation mode, the data in the memory means 34 is read by the terminal unit 30 and sent to the operating device 31 as the optical wireless signal. In either case of the setting mode or the confirmation mode, the data of the received optical radio signal is displayed on the display means 41 in the operating device 31 so that the operator can always check the data. Therefore, with the unique operating device 31 according to the invention, the setting and confirmation of the memory means 34 can be made easily.

In FIG. 5, an embodiment is shown which is substantially the same as the supervisory terminal unit but used as the control terminal unit 50, where a latched relay Ry with primary and auxiliary contacts r1 and r2 is connected to the previous switch ( Instead of the SW and the light emitting diodes LD1 and LD2, they are connected to the signal processor 53 and used. In this case, the load is turned on and off at the main contact r1 of the latch relay Ry, and the ON and OFF states of the load are arranged to be sent to the auxiliary contact r2. Other arrangements and operations are the same as those in FIG. 3, and the same components in FIG. 5 as those in FIG. 3 are indicated by adding 20 to the same reference numerals used in FIG.

The functions set for the memory means 34 and 54 in both embodiments of FIGS. 3 and 5 are the same as previously listed as parameters to be memorized in the memory means.

According to another feature of the invention, there is provided a data setting system in which the terminal unit will be used as a fire and security sensor.

Referring to FIG. 6, the fire and security sensor 70 of this embodiment is connected to the signal processor 73 instead of the switch SW and the light emitting diodes LD1 and LD2 in the terminal unit 30 of FIG. Means (82). Since the sensing means 82 is provided to perform fire, smoke, gas leakage and one or more of two or more detection operations combined with the intruder, the analog output of the sensing means 82 determines whether the detection output is abnormal or not. To the signal processor 73. An alarm signal output means 83 is connected to the signal processor 73 instead of the transmission and reception means 32 of the third embodiment, and any abnormal detection signal is output from the alarm signal output means 83 and the two-wire signal line of FIG. It is transmitted to the central processing unit 14 via 13. Other arrangements and their operation including the operating means 71 are the same as those of the embodiment of FIG. 3, and the same components as those of the embodiment of FIG. 3 are indicated in FIG. 6 by adding 40 to the member number of FIG.

The basic operation of the data setting system for fire and security sensors shown in FIG. 6 will be described with reference to FIG. When the power is connected, the data of the memory means 74 is read to set the function of the fire and security sensor 70, and any input from the sensing means 82 is received and the optical radio signal is received during that time. Monitored according to whether or not. If there is a detection of the optical radio signal, the data of the detected signal is written into the memory means 74 in the setting mode, and then the data of the memory means 74 is read out, and the read data is the operating means (the optical radio signal). 71). When the signal from the operating means 71 is in the confirmation mode, the sensor 70 reads data from the memory means 74 and sends them to the optical radio signal operating means 71. In one of the setting and confirmation modes, the data of the received optical radio signal is always displayed on the display means 81 in the operating means 71 for immediate confirmation by the operator. When the optical radio signal from the operating means 71 is in the alarm signal output mode, the fire and security sensor 70 performs a self-check, and then transmits the alarm signal through the alarm signal output means 83.

For example, in the embodiment of FIG. 6, a correction value or a detection sensitivity adjustment value is stored in the memory means 74 so as to adjust the variation in the detection sensitivity due to any change related to the accuracy of the parts when manufacturing them. It can be included in the set value as data. That is, in adjusting the detection sensitivity at the time of manufacture, the best correction value is stored in the memory means instead of the conventional semi-fixed resistor or variable capacitor so that the calculation is performed in the signal processor 73 with the adopted correction value. Detection sensitivity adjustment can be performed automatically and electrically.

Further, in the fire and security sensor 70 shown in FIG. 6, the arrangement allows the detection level to be most optimally determined to reduce the possibility of false alarms or no alarms, and the time when the detection level exceeds a predetermined value, In other words, it is preferable that the time for accumulating data can be determined. In addition, although the sensing means 82 may be one of several forms, the means of this example is in that the sensing means 82 is set in the memory means 74 and the signal processing in the signal processor 73 is set. It is assumed that the same signal processor 73 can be selected according to the same signal processor 73 so that the same signal processor 73 can be applied to various types of sensing means 82 so that the required parts can be commonly used. In addition, the above-described fire and security sensor 70 may be provided to be directly connected to the two-wire signal line 13 of FIG. 1 in a so-called point address sensor method, in which case the position where the alarm signal is generated can be determined very accurately. Can be. In this case, writing of data in the memory means 74 in the sensor 70 or modification of the data stored therein can be easily achieved from a remote location, and the installation work of the system required for fire and security purposes can be simplified. Will be easily understood.

According to another feature of the present invention, an arrangement for preventing intentional modification of setting data by a third party in writing data into the memory means of the terminal unit can be provided. In yet another embodiment for this purpose, the fire and security sensor terminal units shown in FIG. 6 as well as the monitoring terminal units shown in FIGS. 3 and 5 can be used. Referring to this embodiment with reference to FIG. 8, the code for specifying the system is stored in advance in the memory means of each of the monitoring and control terminal units of FIGS. 3, 5 and 6 and compares FIG. 4 with the embodiment of FIG. As will be apparent at the time, it is determined whether the received optical radio signal matches a particular system code. When a match is recognized, the data is written into the memory means, then the data in the memory means is read out and an optical radio signal is sent to the operating means, but if it is not matched, other operational features of this embodiment are the same as those in FIG. .

Although this embodiment is arranged to write a specific code in the memory means of each terminal unit in accordance with the features of the invention, the arrangement may also be such that a specific code for the system is set in the central control unit 14 as shown in FIG. Therefore, if there is a match between the specific code for the set system and the code provided to the central control unit 14, the code is allowed to be written to the memory means of the terminal unit. In this case, the achieved set mode state is transmitted from the central control unit 14 via the two-wire line 13 to the terminal unit. In the terminal unit, data writing in the memory means is performed as an optical radio signal only in the setting mode, as will be apparent when FIG. 9 is explained.

According to another feature of the invention, measures are taken to carry out the selection and setting of functions in a simpler manner for terminal units, each of which can achieve various functions in common and which can vary in function. Referring to FIG. 10, the terminal unit 90 of this embodiment switches in the terminal unit 30 of FIG. 3 to connect suitable input / output devices or equipment to the means 102a, 102b, ..., 102n. (SW) and a plurality of input / output means 102a, 102b, ..., 102n connected instead of the light emitting diodes LD1 and LD2.

In the optical radio signal Sr transmitted from the operating means 91 to the terminal unit 90, as shown in FIG. 11, not only the setting mode for writing data into the memory means 94 but also the memory means 94 Corresponding to the confirmation mode for reading data from, the management code SL for selecting whether the memory means 94 is in the data setting mode or the data confirmation mode, assigned to the mode type of the function settable for each terminal unit A target code (OJ) specifying the function number, and setting data codes (DT1 and DT2) specifying the set contents of each function are included, and the function numbers specified by the target code (OJ) are paired in the absolute in the memory means. Corresponds to the address one by one. Other arrangements and operations are the same as those in the third embodiment, and the same components as those in the third embodiment are indicated by adding 60 to the same reference numeral.

In particular, the target code OJ specifying the function number is to be designated as one of the input / output means 102a, 102b, ..., 102n to which a plurality of input / output devices are connected as shown in FIG. It consists of a terminal number (NT) indicating acknowledgment and a function number (NF) given to all types of functions that can be set in the terminal unit (90).

Thus, for example, when one of the terminal units connected to the switch in the input / output means 102a is intended to correspond to the other terminal unit connected to the load in the input / output means 102b, the input / output means ( The terminal number NT corresponding to 102a) is given to the terminal unit connected to the switch to set the function of the unit, while the terminal number corresponding to the input / output means 102b is given to the terminal unit connected to the rod and Set the function.

The absolute address of the memory means 94 is set to match the target code OJ, i.e., as shown in FIG. 13, the memory means 94 has a block zone divided for every terminal number NT. Provided, the zones include slots each formed to correspond to each of the function numbers, and setting data codes (DT1 and DT2) are written to each slot. Further, these slots in each block zone correspond to the function number NF in such a manner that "0" address is a terminal unit address, "1" address is a terminal unit type, and "2" address is an input polarity. Is fixedly allocated. Therefore, the absolute addressing of the memory means 94 with the value specified by the target code OJ uniquely designates the slot corresponding to the terminal number NT and the function number NF specified by the target code OJ. will be.

In this case, since the terminal number NT corresponds to the zone number of the memory means 94 and the function number NF corresponds to the address of the slot in each zone, writing to the memory means 94 is performed by the operating means 97. Can be achieved simply by specifying the target code OJ of the optical radio signal Sr from the absolute address of the memory means 94.

Further, when the transmission signal is transmitted from the central control unit 14 of FIG. 1, the slot in which the address is written in every zone is examined, and the terminal unit is in a state where the address sent from the central control unit 14 and the written address match. The function of 90 is set according to the contents of the specific zone to perform a predetermined operation.

The terminal unit 90 is preferably arranged such that the control code data is set in advance according to the purpose of the terminal unit 90, for example, the terminal unit format. That is, the control code data is set to "0" for the wall switch corresponding to each of the rods, for example, and "1" for the switch when the rods form a group in terms of building floors or rooms. 2 "is set for the case where the rod forms a pattern," 3 "for the case where the supervisory input is a non-voltage contact input," 4 "for the case where the control output is a relay drive output, and so on. It is set according to the purpose of use. Further, when the control code data is changed in accordance with the purpose of the terminal unit 90 and the control code corresponding to the control code data is included in the optical radio signal from the operating means 91, as shown in FIG. Since it may be possible to determine whether the function setting will be executed depending on whether the code matches the check code data, no malfunction setting can be prevented by not providing any check code that matches any missetting. have.

On the other hand, the check code data is not necessary to set the address of the terminal unit 90 in determining the function of the terminal unit, and whether or not check is necessary is preferably selected according to the setting contents.

In this case, the operating means 91 are arranged such that the optical radio signal transmitted from the operating means 91 includes a switch signal specifying whether matching between the verification code data and the verification code is to be performed.

When the optical radio signal is to include a switch signal, it is possible to confirm the presence of a match between the check code data and the check code when it is specified by the switch signal that a check is required, but when specifying that the switch signal does not need to match, As shown in Fig. 15, the function setting can be executed unconditionally.

It is also preferred that a call signal is added to the initial stage of the optical radio signal from the operating means 91 such that the terminal unit 90 switches over with the unit ready to receive the optical radio signal.

With the addition of such a call signal, as shown in FIG. 16, it is possible to detect the presence or absence of a call signal while processing the signal transmission and reception on the transmission signal in the terminal unit 90, and when the call signal is present, Transmission and reception of the transmission signal is interrupted to allow the optical radio signal to be received.

Further, as shown in FIG. 17, the response signal is included as an optical radio signal from the terminal unit 90 for the call signal.

With this response signal included, as shown in Fig. 18, it is possible to determine whether the response signal exists within a predetermined time to determine whether the function setting for the terminal unit 90 is normally and correctly performed.

Here, the above-mentioned check code data can be used as the response signal, and in this case, as shown in FIG. 19, the check code data sent to the operating means 91 as the response signal is compared with the check code in the operating means 91. If they match, it is determined that setting is possible and the function setting operation is continued.

When their inconsistencies are detected, the function setting can be interrupted at the moment of detection, and the operator can detect inconsistency of the control code in advance in the initial stage of the function setting operation. When the control code data attempts to set the same function for a number of different terminal units, it is left to the judgment whether the control code data sent as a response signal is in a format that they can set, and if so, the specific control code data is stored in the operating means 91. From each terminal unit 90 to the terminal unit 90 as the control code.

When the check code data of the terminal unit 90 is not clear, the check code data sent as the response signal is transmitted from the operating means 91 as the check code at the time of setting, so that the setting operation of the function can be easily understood. As such, their control codes may be executed for terminal unit 90 even when it is not clear.

According to another feature of the invention, an area setting system can be provided adapted to be suitable when the terminal unit is used as a human body detection sensor unit.

Referring to FIG. 20, in the exemplary embodiment of this feature, the human body sensor device 110 may include an optical receiver device in which an optical radio signal is transmitted from an optical radio transmitter 111 that forms an operation means through a light emitting element 111a. 110a).

The sensor device 110 includes a signal processing means 112, in which the received signal is provided as a detection output of the sensor 115 through an optical radio signal receiving means 113 coupled with the optical receiving element 110a, and the receiving means. And detection area control means 114 connected between the 113 and the sensor 115. In particular, the radio transmitter 111 transmits a detection area signal to the sensor device 110, and the signal is demodulated by the signal receiving means 113, and the demodulated signal is sensed in the sensing direction in the range from the horizontal direction to the vertical direction. It is used to control the detection area as a direction control signal provided from the detection area control means 114 to the sensor 115 to control the detection, thereby achieving human body detection by the sensor 115 for the desired area. The detection area setting as well as the change can be accomplished using the optical radio transmitter 11 at a remote location from the human body sensor device 110.

According to another feature of the present invention, there is provided a sensitivity control system suitable when the terminal unit is used as a fire detection sensor device.

Referring to FIG. 21, in another embodiment of the present feature, the fire sensor device 130 receives an optical radio signal transmitted from a light emitting element 131a of an optical radio transmitter 131 forming an operating means. At 130a).

The sensor device 130 includes signal processing means 132 supplied with a fire detection signal from the sensor 133. The transmitter 131 also transmits a sensitivity and time data signal for controlling the sensitivity of the sensor 133 of the sensor device 130, and the data signal received by the sensor device 130 is an optical radio signal receiving means 134. The demodulated signal is provided to a nonvolatile memory 135 which can be stored so that the demodulated signal is read by the sensitivity-schedule setting means 136.

In this setting means 136, a timing signal is provided from the timer means 137, while the detection signal from the sensor 133 is in response to an output from the sensitivity-schedule setting means 136. Is processed from

The sensitivity of the sensor 133 is 8.00a.m. To 8.00p.m., the lowest (for example, level 0), and 8.00p.m. To 8.00a.m. is assumed to be set by the optical radio transmitter 131 as shown in FIG. Then, the operator initially inputs "0" with the ten keys 131g, confirms this "0" input with the monitoring display, and then displays the display on the display 131b if there is an operation of the sensitivity setting switch 131c. The sensitivity data "0" is erased and stored in a memory (not shown) provided therein.

The operator next enters time data " 800 " by ten keys 131g and confirms this with the monitoring display 131b, after which the time setting switch 131d is operated so that the display on the display 131b is deleted. Allow time data to be stored in internal memory. In the same order, the sensitivity data " 10 " and the time data " 2000 " are stored in the memory, and then the signals of both of these stored sensitivity and time data are transmitted through the light emitting element 131a by operating the transmission switch 131e. 131 is sent to the fire sensor device 130.

The optical radio signal thus transmitted is trapped in the light receiving element 130a of the fire sensor device 130, and the signal receiving means 134 includes the sensitivity data ("0" and "10") and the time data ("800"). "And" 2000 "are demodulated, and the demodulated data is stored in the nonvolatile memory 135. The sensitivity-schedule setting means 136 receives a timing signal from the timer means 137, and when the timing signal matches the time data "800", the sensitivity data ("800") corresponding to this time data "800" is matched. 0 " is supplied to the signal processing means 132, where the alarm output level of the means 132 is modified based on the data " 0 ".

In addition, the sensitivity of the sensor 133 is also changed in the same manner. At this time, the sensitivity data ("0") is maintained until the timing signal coincides with the time data ("2000"). If the timing signal coincides with the time data ("2000"), the sensitivity data becomes "10". It will be at the best sensitivity.

In this example, the sensitivity can be instantly switched irrespective of time by the operation of the transmission switch 131e without the input of the given sensitivity data and the time data, for example by operating ten keys 131g.

Therefore, the present embodiment can also allow the sensitivity and time data from the fire sensor device 130 to be freely modified at the remote location.
